Java does not Work in OPERA 20 !! I check Java side the say CHome is 32 Bit browser Java work only in 64 Bit Browser

Please refer to Oracle as to when they will ship a 32-bit version of their Java plug-in.

When the RSS feeds come back from Opera 12 ?

Their are a few RSS readers available as extensions. Personally, I use the Newsblur web service as a pinned tab in Opera.

Bookmark List also still missing !

This will return in a later version. For now we have Stash, Speed Dials, and the bookmarks bar. There are also plenty of bookmarking extensions (including one by Opera) and web services. Personally, I again prefer Delicious as a pinned tab.

this is the same problem that have google chrome and chromium. Chromium doesn't have a 64 bit version. don't ask me why... this is maybe the main problem with browsers that use chromium like google chrome and opera

Oracle has Java JRE 7+ as a 64bit on OS X and they have a working update checker (the Windows 64bit version does not even have an update checker), the older Apple Java (based on JRE 6) was a mostly 32bit, Apple is pushing users to use the Oracle provided JRE 7 plug in

I am guessing there is a 64bit Chromium in the works for OS X, on Linux there has been one for a while

Tho using the JRE 6 is not the best option for security Oracle does not update JRE 6 anymore, the current JRE 7 has an option to have older JREs be used for some apps that need it, you would have to check the Oracle docs

Java JRE7 does work in Safari (Safari can be loaded in 64bit or 32bit mode) using Safari or another browser with 64bit might be a work around until Chromium gets a stable 64bit

if we find 2 or 3 versions of JP2LAUNCHER and JAVAW when we search, then we must repeat the above for all of them.

in the Configure Java Control Panel Advanced tab we can set "Do not check" certificate revocation and disable security verification. and in the Security tab we may Edit Site List... for the Exception Site List ( add URLs to unblock sites )
